Toallwhomitmay comer-n: 3:-

Be it known that 1, MM; L. ,Snmrsnk, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Motor-Meter Lock, of whi'ch the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a lock for allowing the removal of a radiator cap carrying a motor-meter which will prevent the removal of the motor-meter from the machine.

It will be undertsood by those accustomed tov automobiles that'it is .common to provide the radiator cap with a thermometer, but since the radiator cap must be removed from time to time to place water in the machine it is not easy toso lock the cap as to prevent it from being stolen.

The present invention also afi'ords means to support the. cap and motor-meter while the radiator is being filled.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied. to the same portion throughout, but I am aware that there may be modifications thereof.

Figure 1 is a side elevation of the front end of a radiator filling neck showing the cap and the application thereto of the securing means.

Fig. 2 is a plan view of clamp for embracing the motor-meter.

Fig. 3 is a side view partially in section of the clamp shown in Fig. 2.-- p

Fig. 4 is a plan of the ring which is. se-, cured to the radiator filling neck and Fig. 5 is a vertical sectional vlew of the ring shown in Fig. 4.

The numeral 1 indicates the radiator which has the filling neck 2 and cap 3. The motor-meter is indicated at 4 and consists of a disk like member with the end of the thermometer projecting through and secured to the cap 3. Embracing the neck 2' is a which has an upstanding hollow stud 6. he ring 5 1s soldered or otherwise permanently secured to the neck embracingthe' lower portion of the motor-meter. Over the cap is a hinged clamp consisting of the two arms 7 and 8 pivotally connected at 9 and having the overlapping ears 10, 11 and 12 through which a pin 13 passes. The pin 13 passes into the stud 6 and it has a washer 14 permanently secured to its lower end. The washer 14 may be moved vertically in the stud 6 but can not be removed therefrom.

The result of the foregoing constru tion is that the radiator cap can be rotated in the arms 7 and 8 to place it on the neck 2 or to remove it therefrom, but the cap can not be removed from the radiator although it can be turned around out of the way to fill the radiator.

What I claim is as follows, but various modifications may be made in the construction shown in the drawings and above particularly described form, within the .pur-

view of my invention.

1. A securing device forradiator caps comprising a hollow post, a ring connected therewith for permanently securing the post to a radiator outside the filling neck, a pair of arms adapted to be loosely connected with a radiator cap, and a pin for connecting the-arms together and to said hollow post, the pin being secured permanently and slid- ,able within said hollow post.

2. A securing device for radiator caps comprising a hollow post, a ring connected therewith to be permanently connected to a radiator filling neck outside the-same, apair of pivotally connected arms adapted to be loosely connected with a motor meter on a radiator cap, and a pin for connecting said arms together rigidly, said p-in being slidable and revoluble in the hollow post to allow the cap'to be moved away from the neck to. fill the radiator.

In testimony whereof I have hereunto set my hand this 8th day of March, A. D. 1920.
